Protos 16 was very original F2 design commissioned by driver / engineer Brian Hart to Frank Costin for Ron Harris team. Costin constructed a bonded plywood monocoque with wooden ribs. The lines were very slippery, and aerodynamic refinement was carried through to front suspension and the distinctive cockpit screen. The car was powered by Cosworth FVA, and was overweight, but in its only season, 1967, it was competitive on fast circuits. The best placing of the season was a second by Brain Hart at Hockenheim, in round 4 of the European F2 Championship. The scale model represents the car raced at another event at Hockenheim, II Rhein-Pokalrennen, where Frenchman Eric Offenstadt finished fourth. Offenstadt started his racing career in motorcycles. In 1961 he was French champion in the 175 cc category on Aermacchi. In 1963 he moved to single-seaters driving in Formula Junior. In 1965 – 1969 Offenstadt drove in Formula 3 and Formula 2 for Matra, Cooper-BRM, Lotus-BRM, Protos, and Pygmee. He returned to motorcycle racing in 1970 and raced in Moto Grand Prix until the 1973.
